Welcome the world, celebrity babies! We’re taking a look at the newest, littlest stars in Hollywood and their famous parents.

John Krasinski + Emily Blunt

The former Office funnyman took to his personal twitter account to announce the arrival of his and Emily’s daughter, Hazel, on February 16th. “Emily and I are so incredibly happy to welcome our daughter Hazel into the world today!” John tweeted to his fans. This is the couple’s first child. Krasinski and Blunt married in 2010 and announced her pregnancy in the fall of 2013. Whether little Hazel inherits her father’s humor or her mother’s good looks (or both!), we’re sure that we’ll be seeing her on the big screen someday.

Simon Cowell + Laura Silverman

Who knew that the scariest competition judge in television history would be changed so drastically by fatherhood? Cowell and Silverman celebrated Valentine’s Day with their new son, Eric Philip. The duo’s son was born in New York City and weighed in at 6 lbs., 7oz. Like Krasinski, Cowell announced his son’s birth via Twitter: “very happy to say Eric was born…Healthy and handsome.” Cowell also shared with his fans that he and Laura named their son Eric after Cowell’s father—so sweet! This is Simon and Laura’s first child together.

Jason Goldberg + Soleil Moon Frye

Three’s company for the Goldberg-Frye family! Soleil and husband Jason welcomed their first son, Lyric Sonny Roads, on February 10th. The newest member of the family joins two older sisters, Jagger and Poet. With a name like Lyric, it would be no surprise if Jason and Soleil’s son ended up in the music industry. It was clear that Lyric was going to be a big baby from Soleil’s Instagram photo and he didn’t disappoint—he weighed over 9lbs! Soleil shared her new-mom happiness with fans via Twitter: “Nothing like the first days of your new baby. I’m soaking it all in and I am in love.”
